Interesting idea. Also, DuckDuckGo can do the same:

I also use Google's "I'm feeling lucky" as my default search so I can type e.g. "mdn array" to look up the JS array docs quickly. I used to use DuckDuckGo's version but the results were unfortunately too inaccurate.

Someone on HN mentioned (or even built) http://mdn.io for that, so you can just type mdn.io/array into the address bar and it takes you straight to the right JS docs page.

Bonus: works in every browser or environment.
